To all 'whom it may concern:

Be it known that I, WILLIAM EDWARD BURKS, a citizen of the United States, residing at Kerrville, in the county of Kerr and State of rFerias, have invented anew and useful Means for Raising and Lowering Drill Disks or Flows, of which the following is a speciiication. v

rlhis invention has relationV to means for raising and lowering drill vdisks or plows and it consists in the novel construction and arrangement of its parts as hereinafter shown and described..

The object of the invention is to provide a means for elevating disk drills sufliciently' to enable the drill to be readily transported from place to place and over low underbrush, stumps and rocks without danger of the disks being damaged by engaging such obstructions. Means is also provided for raising and lowering the disks while they are in contact with the soil.

In the accompanying drawing: Figure -1 is a top plan view of a drill providedwith the raising and lowering means. Fig. 2 -is a transverse sectional view of the drillcut on the line 2-2 of Fig. 1 showing'thevdisks in lowered position. Fig. 3 is a transverse sectional view of the drill cut on the line 2-2 of Fig. 1 and `showing the disks in elevated position. Fig. 4 is a sectional view of an end portion of the drill cut on the line 4-4 of ig. 1. Fig. 5 is a transverse sectional view of a brace used on the drill and cut on the line 5-5 of Fig. l. Fig. 6 is a perspective view of an arm used in the mechanism.

The drill consists of the frame 1 which is sup orted by the ground wheels 2. The see boX 3 is mounted upon the frame 1. The bar 4 is supported under the forward portion of the frame 1V by the dependingbrackets 5. The forward ends of the beams 6 are pivoted upon the bar 4. The disks 7 are liournaled upon the rear end portions of the beams 6 and the boots 8 are located adjacent the said disks. Plow points (not shown) may be substituted for the disks 7 if desired. The liexible tubes` 9 lead from the seed boX 3 to the boots 8 in the usual manner. The segmental guides 10 are located at the rear portions of the sides of the frame 1 and are ,provided with the curved elongated slots 11. The bar 12 is located at its ends in the slots 11. Said bar is provided at intervalswith the lugs 13 which are connected by means of the links 14 with'the boots 8. -A lever 15 is iiXedly mounted upon the bar 12 and is adapted to turn the saine axially whereby the lugs 13 will be swung and the links 14 will be moved longitudinally which will cause the disks 7 to operate deep or shallow in the ground as desired. l

The latch plates 16 are pivotally attached tothe side pieces 16 of the frame 1 and are provided with notches 17 which are adapted to receive the end portions of the bar 12. The sleeves 18 are slidably mounted upon the end pieces of the frame 1 and are adapted to be slipped over the free ends of the latch plates 16 and when so positioned are secured in place'by the pins 19" which are passed vertically through the said sleeves and the pieces 16 of the frame 1. lhe shaft 20 is j ournaled for rotation between the upper end portions of the guides 10 and the brace rods 21 are attached at their forward. ends to the forward portion of the frame 1 and ass transversely through the seed box 3 andp are provided at their rear ends with bearings which receive'the shaft 20. The braces 32 are made up of front and rear sections which are normally held together by pins or bolts 23. The rear sections of the braces 22 are provided with perforations which receive the ar 12 and the forward sections of the said braces are fixed to the frame 1.

A gear segment 15 is mounted upon the rear portion of the arm 22 which is located near the middle of the drill. The said arm 22 is pivotally attached by means ofthe bolt 23 to the arm 24 which is iixed to the frame 1. The shaft 12 passes through the arm 22 and the lever 15 is mounted upon the shaft 12 adjacent the segment 15 and is provided with a pawlmechanism adapted to engage the said segment whereby the lever is held in iixed position with relation to the arm 22.

The shaft 2O is rovided with a squared end 24 which is a apted to enter a similar socket provided in a crank handle (not shown). The ratchet wheel 25 is iiXed to the shaft 20 and the pawl 26 is pivotally mounted upon oneV ofthe guides 10 and is adapted to engage the said ratchet wheel 25. The forward ends of the chains 27 are iixed to the shaft 2O and the rear ends of said chains are iiXed to thelar 12.

When it isdesired to elevate the disk 7 are removed and the sleeves 18 are slipped longitudinally along the end pieces ot the frame 1. The latch plates 16 are then swung bacli upon their pivots. The pins 23 are removed trom the braces 22 and the shaft 20 is rotated by means of a crank handle which is applied to the squared end 24 thereof. As the said shaft 2O rotates the Chains 27 wind thereon and the bar 19 is drawn toward the shaft 20. As the said bar moves along the slots 11 the rear ends oi the beams 6 are elevated through the coni'iec'ting links 14. To lower the rear ends of the beams 6 the operation alcove deserihed is reversed. It Will be oiserved that during l the process of raising and lowering the l: ar 12 l and its connections the greater portion of the stress is borne by the brace rods 21 which are fixed at their forward ends to the j frame 1 and whieh are provided with eyes i or bearings which receive the shaft j. l Vhen it is desired to adjust the boots S i vertically,y without moving' the bar 12 l l bodily along the guides 11, the Operator swings the lever 15, which turns the said bar 12, and the lugs' 13 are moved in vertical lanes which, in turn move the links 1;

1. Anv implement as described comprisingl a frame ivoted beams sua orted there?.` l

7 f 1 f and carr une eartn enea me' elements kD op b 7 Guides mounted u on the Irame. a bar en- D l gaging said guides, links connecting the bar l with the beams, a shaft journaled l'or rota.- tion between the guides, lirace rods having eyes which receive said shaft and` whieh are attached at their ends to the l'rame and ileXi'tle elements connecting the shai't with the bar.

2. An implement a irame, a seed liox pivotally supported lry the traine and having earth engaging elements, guides mounted upon the traine and connected with the seed box, a tar engaging said guiiles, links connecting' the tar with the leains, a. shaft iournaled for rotation letween the guides, trace rods attached at their l'orward ends to the trame and passing transversely through the seed box and receiving said shaft and ilexiiie elements connecting the shalt with the har.

3. An implement as described comprising a iranie, beams pivetally supported therebyy and carrying earth engaging elements, guides mounted upon the i'ranie, a lar engaging' the guides, links connecting the bar with the ljeains means l'or moving the har along the guides, latch plates pivotally attached to the trame and having` notehes tor the reception elE said liar, and sleeves slid al ly mounted upon the frame and adapted to receive the free ends ol said latch. plates.

In testimony that i claim the foregoing` as my own, l have hereto ailixed my signature in the presence ol two witnesses.
